Futures Trading
It's hard to predict what products, technology, and systems will be important in the next 10 years, but green experts say the looming energy crisis can give us a pretty good idea.

Yogi Berra, the Hall of Famerknown for his paradoxical observations, once said famously, "It's tough to make predictions, especially about the future." Indeed it is. But with all due respect to Mr. Berra, sometimes all you have to do to see the future is look around and see where there is a need, where opportunities lie, and where there will be challenges. As management guru Peter F. Drucker put it, "The best way to predict the future is to create it."
Some well known examples can be seen at Amazon (the Kindle) and Apple (the iPod). These companies understood that in an increasingly mobile world, consumers will want to transport more than one book or magazine at a time or be freed from the burden of carrying CDs.
Consumers have needs and wants for their homes, too. It's obvious that the world's growing population will require more energy and natural resources such as oil and water, which means that providing sustainable homes that use less energy and water is likely to be a continuing preoccupation for the industry. Less obvious, however, is what products, technology, systems, and practices will best accomplish this?
We decided to ask the people who pay the most attention to such things—sustainable builders, consultants, green building program officials, and LEED-certified architects—to look into the future and tell us what they see. We also gathered some of the best new ideas that keep popping up in our inboxes.
From these, we've compiled a list of 10 ideas that we think will be important in home building in the years to come. The collection is a sampling of ideas that will be pivotal in the future, but these are by no means the only ones. Take a look at our picks and let us know which of them you think will be important to the future of the home building industry.
1. The house will function as a system.

"I think a piece of what green building is getting us to is not just building a house stick by stick or brick by brick but really looking at it as a system," says Amber Wood, program manager for energy efficiency at the NAHB Research Center in Upper Marlboro, Md. Simply put, everything in a house is connected. So, if you insulate better, you can use a smaller HVAC system. If you design your plumbing runs efficiently, it will save energy on heating bills. Though building scientists have been preaching about these connections for years, not many builders have paid attention. But Wood says manufacturers are making it easier for the industry to accomplish. "There are various products and different wall types and sections that are available now that I think will become more popular," she says. "A lot of the products are going to be integrating various pieces [of the system], including air sealing and insulation in the wall."
2. Modular goes mainstream.
Some builders use a fair amount of panelization for floor and roof trusses, but usage could be much higher. Carl Seville, green builder and consultant, believes this will change. "Anything like SIPs and other panelized systems that will help cut the time of building a house and improve the quality should get more popular," says the owner of Seville Consulting in Decatur, Ga. There is no debating the benefits: less waste, faster construction, fewer moisture problems. These systems may not necessarily be cheaper, Seville says, but they will result in less site management. "Builders are slow to change, but modular and panelized systems have the potential to be huge in the industry."3. Air sealing becomes easier.
4. Water turns political.
5. Solar becomes accessible.
Solar installations are costly and often unsightly. But a new crop of solar-integrated roofing products from such companies as Dow Building Solutions, CustomBilt Metals, CertainTeed, and others are taking steps to change that. Roofing manufacturers' involvement in solar makes the systems easier and cheaper to put in place because they are installed at the same time as the roof. The seamless design of these solar-integrated products also means they will be a little more attractive. CertainTeed says it is "transforming a niche technology into a product that is more accessible to the building industry and, therefore, a broader range of homeowners."6. High R-value windows become the new Energy Star.
When President Obama signed the American Recovery and Reinvestment Act of 2009, it gave homeowners a 30 percent tax credit for qualified energy-efficient home improvements, including replacement windows that have a 0.30 U-factor and a 0.30 solar heat gain coefficient. This might just be the beginning. "Dual-pane windows were invented back in 1865. So in 1870, they were truly best of class," Kevin Surace, president and CEO of Serious Materials, told the Democratic Caucus Job Summit in January. "But I am thinking, 140 years later, and we call that energy efficient?" Serious Materials is calling for windows to be R5 or higher. "Surely R7+ will be standard," Surace says. "[It] may be code driven or simply energy-cost driven." The DOE and the American Architectural Manufacturers Association (AAMA) agrees. To help lower costs for the windows, the DOE is eyeing a volume purchase program of R-5 windows and low-E storm windows, as a way to expand the market. "Even though the energy benefits of R-5 windows are exponential, their current cost inhibits their widespread acceptance," says Rich Walker, AAMA president and CEO. The DOE program should make them more affordable, he says.7. Hybrid water heaters heat up.
Though tankless water heaters are said to be highly energy efficient, many consumers and builders aren't convinced and prefer their traditional units. Manufacturers such as Rheem, GE, and A.O. Smith are now introducing a new class of hybrid products that offers the benefits of both tank and tankless systems. Using various types of technology, the products heat water like a tankless product, but they also contain a reservoir like a tank unit. In some cases, the efficiency rating of some units is as high as 90 percent, meaning they are Energy Star rated and eligible for the federal tax credit. Energy efficiency is the driving force behind innovation in the water heater industry, A. O. Smith says.8. Agricultural waste comes home.
